Product details
General
SBJ type deep water aerator & mixer combines aeration and mixing in one machine, it is specially designed to work for the water treatment process with high organic concentration wastewater and the process requiring high oxygen transfer rate. It is often used in nitrification tank, denitrification tank, SBR reactor, sludge tank, oxidation pond, or other processes which need aeration and mixing in deep water and high oxygen transfer rate.
The equipment is designed with a dual-speed motor, which makes the equipment able to work as an aerator at high speed, and as a mixer at low speed, the maximum working depth underwater can reach 20m.
Key Features
- Main conponents:
SBJ deep water aerator & mixer consists of submersible motor, gearbox, stator assembly, rotor assembly, mixing chamber, base assembly, air inlet pipe and hoist chain, as following:
- Deep water technology:
Deep water sealing technology is used for submersible motor and gearbox, the maximum working depth can reach 20m, it makes a much deeper aeration tank feasible. The advantages of a deep tank are that, the footprint of aeration tank is much reduced, air pollution is reduced, also the air retention time in water is long, and oxygen transfer rate is high.
- Aeration function:
Aeration is achieved by air supply system and high speed rotation. As long as the ratio of air / water and working time is controlled well, a stable and continuous aeration performance will be achieved. In practice, dense and evenly distributed air bubbles can be seen on water surface.
- Mixing function:
The impeller is open type and free of blocking. After high speed aeration mode the equipment can be automatically switched to low speed mixing mode, water flow velocity at impeller periphery can reach 3-5m/s, plus flow reflection on tank wall, water circulation will be generated and sediment can be prevented.
- Easy installation:
SBJ aerator & mixer is positioned by gravity, installation is quite easy, except a crane, no other accessories are needed, no need to dry the tank or stop production.
- Low investment, low operation cost, easy maintenance
- Dual mechanical seals and electrical protection function make it reliable and work safely
